Abstract
We show that the following double integral ∫0πdx∫0xdy11-pcosx1+qcosyremains invariant as one trades the parameters p and q for p′=1-p2 and q′=1-q2, respectively. This invariance property is suggested from symmetry considerations in the operating characteristics of a semiconductor Hall effect device.
